ATTACHMENT FOR SPOOLING OB WINDING MACHINES.

To all whom it may concern:

Be it known that I, GEORGE A. METGALF, citizen of the United States, residing at Woonsocket, in the county of Providence and State of'Rhode Island, have invented new and useful Improvements in Attachments for Spooling or Windin Machines, of which the following is a col cation.

My invention has relation to yarn s ooling or winding machines; and it contemp ates the provision ofa simple, reliable and easilycleaned attachment for such machines, constructed with a view of receivin the yarn en route into the machine, and reakmg the yarn when a knot, bunch or analogous imperfection occurstherein, in order to prevent the knot or bunch entering the machine and causing imperfect work.

My invention also contem lates utilizing thementioned breaking of t e y'arn to put into action astop-moti'on mechanism connected with the machine, but inasmuch as said stop motion mechanism forms no cost of my invention and may be of the conven tional orother suitableconstruction, I havedeem it unnecessary to illustrate the same.

With the fo oing in mind, the invention will be fully on erstood from the following description and claims when the same are read 1 I l connection with the drawings, accompan yingblan forming part of thisepecification, m wch:

Figure 1 is an elevation, p'artly in section, illustratinga knot=arresting and yarn;breaking attachment constituting a practical embodimentof my invention, as. the same oppears when properly positioned on a-- bai 'of a-spooling or machine. Fig.2is a plan-view of theatta'chment. Fi 3 isqen elevation taken at wright angllljlteo ig: r nd showing one side ofthe-attac is a view similar to Fig; 3sl1owingthje oppm site'side of the attachment.

lengthwise of the frame of a spooling or mindmg machine, and B is the bod or main frame of my attachment. The .ovver ortionoof the said bodyisbifurca-ted to stra dle the bar A and is provided in one side with a. threaded a erture to receive a. screw b through which the body is preferably fixed on the bar.

C is an eccentric bushii arranged on and connected by a screw 0 to L 1e side of the body A, and having an upwardly extending and outwardly flared fil er-piecc and yarn-guide d, and D D are (his mounted on the said bushing and preferably shaped as shown in cross-section. When necessary one or a glaurality of spacing Washers such as E may arranged on the bush C and between the disks D, as shown. T e part d isdc nominated a fin'ger piece and yarnuide iria'smuch as it' serves for the mani u aftion of the bushing C to raise or lower t e disks D, and also serves. to facilitate the threading of the attachment c., the plsci of the yarn in proper positionwith res ect t creto. B raising and lows the isks'l); as state the operator is enal) ed to re late the go'sitien of the same relative to t e point 0 the yam-breaking device or needle G to suit yarns of difierent kinds.

F is a tuhularrock-shaft journaled in the upper portion 0 of body B and having an enlargcmcnt at its forward end in which is a diametric bore terior thread 72 in its rear portion.

G is" the 5am breaking device of the attachmentw ch is preferably in the form of a needle, and extends through the bore 9 of sha'ft'F- dew-'1iwerdlyv to a point between the D.

H isfa thumb screw a ed in the rear threaded ortion of the shaft and I, a rod disposedm the shaft F and between the screw H 'and' the em breaking device G and liavinglhfits' o "co to bind and adj ustably fix theflatter in the bore 9 of the'shaft. At thebaclrobthe body B a collar mounted and also having an inemulsions-earn, andheeringin a-thrca-ded ggerture of said sellerand set must the Fi -med K'wliich'servcs to downwardly to a'point in rear of the bifur-, cated-bodgdportion a and is, yicldmgly held a ainstsai bod rtion. a. spring M w 'cli'is coiled clihu l a latcrlil projection m on the body B, and has an arm which bears against the body and another arm which bears against the rod K. By virtue of the construction just described, it u ill be nuunfest that the yam-breaking device G is normolly held against movement in the direction in hieh am is fed through the uttnehment, Fl". 3. ul when it is necessary to remove collected lint from the disks and yurubreaking device, the said rod ii may, against the action of the s ,ring M, be readily su'uir away from the b0 y portion a so as to roe-i2 the shaft F and en ing the pointed end of the yarn-breaking device rearwardly from its normal and working )OSltiOu bet-seen the disks D. It will also e manifest from the foregoing that the s nee between the disks D may be increased y placing washers such as described between said disks, and vrhile the attachment is in use, the disks may be f quickly adjusted, relative to the yarn brcaking device, to meet chfi'erent conditions as the same arise.

In the practical use of my novel attach ment, the yarn is fed between the disks D l and between the point of the device G and 1 the perimeter of the washer in the manner E and direction indicated in Fig. 3, and so long as the yarn is free from knots, bunches or the i like it will freely pass through the attachment and into the spooling and winding machine. When, however, a knot, bunch or other inierfection in the yarn brings up sgainstthe Series G the said dcvic" vrid break the yarn.

In addition to the advantages hereinbefore ascribed to my novel attachment, it will be noted that the yam-breaking device G is susceptible of vertical adjustment, and that when portions of the disks D are worn by the p e of yarn between the same, the screw 0 may e loosened and the disk turned to present fresh or unworn surfaces to the yarn.

The construction herein shown and described constitutes the best tactical embodiment of my invention of w ich I am cognizant, but it is obvious that in the future practice of the invention such chan es or within the scope of m invention, as defined in the claims appends Having described my invention, what I claim and desire to secure by Letters-Patent, is:

1. A knot arresting and yarn-breaking attachment for spooling or winding machines and the like, comprising suitably-supported means forming a channel for the passage of yarn, cavern-brec-kin?l device extending into the sci channel, an means for positively holding said device ainst movement in the direction in which t e yarn is fed and for yieldingly holding the device to its work and against movement in the opposite direction.

2. A knot arresting and yum-breaking nttu-chuient for spouting or winding machines and the like, comprising suitahl \'supportett, spaced disks adapted to he turned to present fresh surface.. to the yarn, o.- yum-breaking device extending into the space between the disks, and means for positively holding said device against movement in whiehlhc yarn is i'ed and for yicldingly holding the device to its work and against movement in the oppositcdirection.

3. A knot arresting and yarn-breaking attuchinent for spooling or winding machines, comprising suitably supported and adjustable eccentric means, disks mounted thereon,

and a suitably supported yarn-breakin" device extending into a space or channel between the disks.

4. A knot arresting and yam-breaking attachinent for spooling or winding machines, comprising suitably supported and adjustable eccentric means having a finger-piece and guide, disks mounted on said eccentric means, and a. suitably supported yarn-breakmg device extending into a space or channel between the disks.

5. A knot arresting and yarn-breaking sttachment for spooling or winding machines and the like, comprising a body, disks carried thereby, a rock-shaft journcled in the body, a. yarn-breaking device adj ustably iilicti m smd i-ookshuit, a rod connected with the rock-shaft and adapted to bear against the body and prevent movement of the yarnbreaking device in one direction, and means for yieldingly holding the .rod and the yarnbrealnng device against movement in the opposite direction.

6. A knot arresting and yarn-breaking at tachment for spooling or winding machines and the like, comprising a body, an eccentric bushing having a. fin er-piece and guide a. screw connecting sci bushing to the body, disks mounted on the bushing, a. rock-shaft journaled in the body, a yarn-breaking demodifications may be made as fairy fall 5 rection, and means for yie dingly holding the rod and the {am-breaking evice against movement in t e opposite direction.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
